Working Theory

Thanks to the unique and patented 360-degree electrode design, higher engine power output, dazzling engine response and amazing acceleration are implemented through better fuel energy utilization. These Direct Bikes JL50QT-7 racing sparkplugs are designed to help you improve power, mid-range torque, launch time and acceleration to further increase fuel consumption. Our bike Direct Bikes JL50QT-7 racing spark plugs' design ensures optimum mix ignition in the cylinders and warrants more HP compared to traditional projective tip sparkplugs and other brand motorcycle performance plugs. The 360-degree electrode Direct Bikes JL50QT-7 plugs outperform even the iridium spark plugs in regards to firing energy, extra engine performance as well as service life. While traditional bike sparkplugs’ constantly thriving deposits spoil the spark discharge, no soot will be deposited on 360-degree motorcycle spark plugs’ electrodes, because throughout the life of the spark plug the gap size remains as it was originally, apart from normal wear and tear. Because the plug gap is not shielded by the conventional side electrode, exposing the mixture to physically unlimited ignition, combustion speed will increase and flame front spread can take place more easily, and especially more quickly. Easy engine start is attributed to this effect. The subsequent increase in medium effective pressure within the engine cylinder also contributes to added engine pony and optimum bike fuel efficacy. These Direct Bikes JL50QT-7 multi-spark sparkplugs are made for extreme operating conditions and high output; there is simply no competition for the Brisk 360-degree plugs.

360-degree electrode design provides an unrestricted full potential spread of the flame front, which is accomplished by a state-of-the-art retracted ground electrode. Unlike ordinary sparkplugs, where discharge is constrained by the ground electrode, Brisk Direct Bikes JL50QT-7 racing series spark plugs feature an electrode layout where the ground electrode is retracted, so the spark discharge occurs at the very tip of the spark plug. Traditional spark plugs' ground electrodes restricts the natural spherical expansion pattern of the flame front whereas our High Performance Direct Bikes JL50QT-7 spark plugs take the advantage of surface spark discharge, along with retracted ground electrode designed, to ensure maximum spark exposure and unrestricted flame front expansion. Due to stronger spark discharge, a spark can more easily trail along the surface of the insulator than having to break through the air gap. Roughly 70% of the spark travels between the electrodes along the surface of the insulator, also bear in mind that the spark front line is drawn on the whole perimeter of the ground electrode in 360-degree, thus the volume of the spark discharge is maxed out, while not requiring much higher ignition energy supplied by the ignition system. Therefore this motorcycle Direct Bikes JL50QT-7 high-power plug works conjointly with stock ignition and no upgraded coil or performance ignition lead is mandatory accordingly. 360-degree multi-spark spark plugs use the highest quality materials, are produced in European state-of-the-art manufactories and in a never-ending effort to improve upon success, Brisk has also developed electrode technology that is far superior to all others in function and form.

The protruding compact electrode design concentrates the spark deeper in the chamber, guaranteeing fully symmetric and effective spark discharge in the combustion chamber without any undesired turbulence, which is common on regular projective tip spark plugs and which in fact negatively affects volumetric flow. Our dyno-tested Direct Bikes JL50QT-7 high-performance spark plugs give some additional pony besides reducing fuel consumption thanks to the state-of-the-art, 360-degree, round electrode. When designing a plug, several technical factors must be taken into careful consideration. Yet during the engineering phase Brisk decided to merge new technology which leaves all other spark plugs outdated. These Direct Bikes JL50QT-7 high-performance spark plugs are the only specified performance multi-spark plugs in existence. Their lifespan is 25K miles - 40K km or 500-600 hours. In the long run they pay for themselves.

The massive ground electrode provides unprecedented heat dissipation relative to conventional motorcycle plugs, improving the resistance against pre-ignition issues and electrode burn-in. These Direct Bikes JL50QT-7 spark plugs work with factory as well as upgraded ignition. Created for a super high performance, with no compromise ignition, these deliver the highest overall performance to the spark gap over any competing design guaranteed. Our Brisk 360-degree Direct Bikes JL50QT-7 plug is the perfect choice to replace your bike engine’s sparkplugs. Balancing smooth engine characteristics, high efficacy, improved fuel economy and extended change intervals during all required engine demands. The patented multi-spark effect promotes the ignition, ensuring instant ignition and a rapid burn. Our Direct Bikes JL50QT-7 bike racing spark plugs listed on magnum tuning website are intended to replace stock spark plugs. If you need a spark plug of a different heat range than stock, please contact us.

Depending on engine specs electrode design varies. Customer receives that dyno-proven design best fits to the current application according to tests.

This bike performance plug is stocked with different heat range as well. The item you purchase replaces factory spark plug only. If you need different heat range or should you come across any question, feel free to ask our Tech Support Specialist. Customer Service is our number one priority.

This spark plug works well with stock ignition. It replaces factory heat range spark plug only. Are you in the market for colder or hotter plug? Don’t hesitate to contact our product specialists.

What does Heat Range refer to? Heat range indicates the thermal characteristics of a spark plug, or how 'cold or 'hot' a spark plug is. The term cold or hot is commonly used to describe whether a spark plug heats up easily (meaning hot) or whether it provides resistance to heating up (cold). In general, low power engines such as small scooters, power saws, lawn mowers don't produce a large amount of heat, hence use a low heat range also referred to as hot spark plug. This means the spark plug will heat up quickly and reach its optimal operating temperature easily. High performance engines on the other hand produce a large amount of heat, hence a high heat range referred to as cold spark plug. Cold spark plugs are used to resist the heat developed by the engine. However there are exceptions besides several other factors influence the heat range of a spark plug so we highly don't recommend you to swap your factory heat range without professional advice.

true believer in the Brisk racing plugs

I had such a wonderful performance increase with brisk plugs i purchased from these guys that my fellows honestly thought it was at least a 100cc+ increase in horsepower. The bike was reborn. I am a true believer in the Brisk racing plugs. Fantastic plugs and Im gonna promote it.

notable change in acceleration

plug arrived safe and sound yesterday, it fit like a glove and i see notable change in acceleration, price is absurd though, bottom Line yes, i would recommend this to a friend if he robbed into a bank they day before

i didnt regret

From reading other reviews in competitors' web site i was worried that this plug was going to be a scam but after torquing in the plugs i was convinced and i didnt regret i was talked into this purchase. Recomended! Cheers from Alaska

good spark for the money

I pretty much use NGK sparkplugs in everything unless it is a scooter that is starving for more power and I have performance plugs available. I ordered plugs from magnum and received them in 3 days in great condition. Though it is expensive at the first sight, in the long run you get good spark for the money. Bear in mind you can save on gas.

banging plugs

Bought a set just over a year ago now, my bike runs smoother, more crisp acceleration, way better economy, have just purchased a set for my 04 Harley Davidson sportster , can't wait, thankyou very much Magnum tuning, excellent excellent customer service, no1 , cheers bigdave
